[go-nuts] How to execute a command using root?

Hi, I need to execute a couple of commands in golang, the code is roughly as below, cmd := exec.Command(executable, newArgs...) if env != nil && len(env) > 0 { cmd.Env = env } outMsg, err := cmd.CombinedOutput() if err != nil { .. } Executing the

[go-nuts] Questions related to mock exec.Command in unit test

Currently I am using the following code to mock the exec.Command. But there are two issues: 1. I expect the code being tested gets the expected output message (value of the variable 'msg') from STDOUT, but actually what it gets from STDOUT is always "PASS", which should be the output of the

Previously it took a long time to read through the golang spec of version of Jan 14, 2020. The newest golang spec is Version of Feb 10, 2021. I really don't want to read through all the spec again. Is there a summary on the changes between the two versions? Thanks. -- You received this

I tested the program on both Linux and Mac, and the behavior is consistent. Makes sense, Looks like an expected behavior. Thanks. Just paste the program as below, package main import ( "fmt" "os" ) func main() { f, err := os.OpenFile("/tmp/db", os.O_RDWR | os.O_CREATE, 0666) if err != nil

Re: [go-nuts] [generics]The ability to allow different length arrays and slices

Clearly that's a workaround though. Like how you can copy a slice of bytes without calling copy by casting it to a string and then back to []bytes. It gets the job done, but it's weird and not obvious. On Wednesday, July 15, 2020 at 12:14:19 PM UTC-7, Axel Wagner wrote: > > Why not just

Thanks for the feedback. I'm only vaguely familiar with graphql. From my understanding, it's meant to facilitate data query for the frontend dev. But I'm looking at things more from a user perspective here, see my github example. I might have to dig into this though. Le vendredi 2 mars 2018
